This version brings updates to the way custom textures are made — it allows you to make over 1,000 custom textures!
However, because of this, you will need to update your texture packs in order for your custom items to keep having the correct textures. Otherwise, your custom textures will no longer work.
To do so, download this zip file:
https://s3.amazonaws.com/projects.store/spigot/CustomItemsModelFiles.zip
and place the two things in it into the assets/minecraft/models/item folder of the resource pack.
Do
not modify these files at all.
We're really sorry about making a breaking change, and will do our best to not make one in the future. However, this should be the final breaking change to textures.
If you need any help updating, please let us know!
